Application filed October 10,1906; Serial No- 338,260.

To all whom it may concern:

Be it known that I, SIDNY B. YERroN, a hitizen ofthe United States,residing at Seattle, in the county oiKing and State of Washington, haveinvented certain new and useful Improvements in Repeaters forPhonegraphs, of which the following is specification. This inventionrelates to phonographs and other talking machines; and its object is toprovide a mechanicthe music rendered by the reproducer may beautomatically repeated either in-whol'e or in part.

7 With this end in view the invention consists in the 1 novelconstruction, and combination of devices as will be hereinafterdescribed and claimed.

In the accompanying drawings forming part of this specification, Figure1 is a front elevation of a phonograph with devices embodying myinvention attached;

' ;Fig. 2 a fragmentary plan view of the same with the reproduceromitted; Fig. 3, an enlargedplan view of a portion'of the apparatus;Fig. 4, a front elevation of the parts shown in Fig. 3 with. a part ofthe frame work broken away; and Figs. 5, 6 and 7, detail perspective wasof parts of the invention shown detached.

In saidldrawings, the reference numeral- 10 indicates passing about'a'pulley 13 upon the spindle 14. This spindle is journaled insuitablebearings of the frame, is

- anut Tand'connecting' .parts18 to feedthe sound refinelyscrew-threaded, and carries upon an extension a cylinder 15 for therecord 1 6. The screw serves through producer-d9, containing thediaphragm and a stylus, er

I thatthe latter will follow the helical indentations of the record, andis prevented from unduly bearing upon the record by a block 20 slidableon the striaght-edge 21 of the frame 10. All of the aforesaid parts are,or may be,

of ordinary construction, found incertain classes of pho- Detachablyconnected to the block 20, by a set screw 22, is 'a casing-likestructure 23 provided with a rearwardly protruding finger 24, and adownwardly extending,ear 2-5 whereto' is fulcrume'd, by screw 26 a bell--crank 27 having a lateral arm 27, a pendent arm 27, and a lug 27"disposed oppositely of the first named arm and arranged to contact withthe bottom of the cas ing, tolimitfthe swing of the crank in onedirection. 'Thearm'27ffearries an anti-friction roller 28 positionedimmediately above said straight-edge 21 and adapted wh enforced by theaction ofthe bell-crank thereagainst to ,elevatethe-lbloclr 20 and soraise the stylus from the against the crank arm 27 through the action ofa suitable spring, such as 31. When the block, as above stated, iselevated, then the arm 30 of the crank 29 is I correspondingly raised,and when above the height of scribed.-

Adjacent of the straight-edge 21 and extending longitudinally of theframe 10, is a drag-bar 32 which is slid ably seated at one endin asupport 32,- the latter de tachably connected to the frame, while theother end is connected with the motion controller of the repeateractuating devices.

Adjustably seated upon the bar 32 and to the left hand side of therecord cylinder, is an attachment 33, see Fig. 6, which is secured inpredetermined adjusted positions by means of a set screw 33, and has atits front a protruding lug 34 positionedso as to interfere with thecrank-arm 30 when the retrograde travel of the reproducer has caused itto be brought to the terminus of its reverse course, as controlled bythe positioning of said the crank-arm 27 is thrust thereabove by theforce of said spring, and maintains the blockin such raised. positionuntil the crank 29 is tripped, as-presently deslidably seated upon saiddrag to the right hand end of the record cylinder, and is secured inadjusted position by a set screw 36 which, for convenience in manipulating is employedin an auxiliary attachment 37 towards. the oppositeend of the bar, and these last mentioned attachments are operativelycoupled together by a-reach-rod 38, as shown in Fig. 1.

The attachment.35 is provided with a forwardly extending ear 35 for thepurpose of forming an abutment against which the finger '24 of the shellwill strike at respectively, are pointers 39 and 40. which are used inindicating the exact positions at which the attachments ar'e to belocated to effect the purposes before egrplained; for example,theattachment 33,would be set so as to present the pointer 39 at thebeginning of the indentations of the record the music of which isintended to be repeated, while the other attachment 35 is set with itspointer 40 at the end of the music.

Referring now to Figs. 1, 3 and 4, showing mechan- I ism'forautomatically actuating the return movements of the reproducenandraising and lowering the same clear of and upon the record, 41 is acontaining case adapted to be secured to the box 11 in any suitablemanner, as by a clip 42 introduced between the cover driven from a powerspringAS' upon a winding arbor 44, and imparting motion through the gearwheels 45 and =1 it to an arbor 47 carrying a worm wheel 48 engagin; aworm pinion 49 upon a longitudinal arbor 50, whereupon is a speedretarding fan 75. The arbor 47 likewise rotates. through wheels 52 and53, anarbor 5-1. which in turn is geared by wheels 55 and 56 with anarbor 57, the latter having fixedly mounted thereon all eseapement asand a cam 59. A plate 60 reciprocally seated upon supports, such as 61,within the easing. is provided with anotch 62, and is shifted from sideto side by means of the aforesaid drag-bar 32 to permit of the arms ofthe eseapement successively passing through the slot, and its motionintermittently arrested by the arms of the escapement being individuallycaught by the plate upon either side of the notch. An advantageousconnection between the plate 60 and the drag bar is the employment of avertically disposed "rod (33 carried in bearings (34, and provided withbent ends it and 66 which are respectively engaged with the plate bypassing through a notched flange 60, and with the b ar by formingacrank-pin extremity 66 to receive an eye 32 of the bar. The arbor 47has mounted thereon a normally loose spool 67 which upon occasion iscoupled therewith by clutch elements 68 and 69 respectively formed onthe spool and a peripherally 25 perimeter of said cam 59 which, beingelliptical, will' in rotating alternately thrust the clutch element 69out of mesh with the other element against the action of a spring 72,and then allow the latter to assert itself to again couple suchelements. 73 is a flexible line having one oi its ends at'lixed to thespool and passing through an aperture of a fair-leader 76 has its otherend connected with the pendent arm 27 of the bell crank 27, whereby, theline is wound about the spool, it serves to tilt the crank arm toelevate the block 20 iro n. the straight edge 21 and by a contintiedaction retracts the reproducer. 74 is a brake-spring pressingfriction-ally against said spool to prevent the latter brought intojuxtaposition with the attachment 33 by pushing it along toward the'leitby finger pressure exerted against ,the crank-arm 27, or by moving thebar 32 to the right to actuate the repeating mechanism. 1n either casethe reproducer is raised sufiiciently to perin it the spring-pressedcrank-arm 30 to be engaged with "the arm 27" and holds the reproducer insuch elevated condition until disengaged by the impinging of the armlit)" against abutment ill, with the resultant lowering, as beforecxplained, of the iced nut 17 and the reproducor. 7 into operativeengagement; with the screw spindle and with its stylus upon the record.The striking of the abutment. also i'orccsthe drag-bar to he moved toshift the notch oz of plate (30 across the plane of the escapement wheelarms, meanwhile allowing -this 'wheel to make a partial rotation,- andthe cam fitlbrought to present one of the ends of its major diameteragainst the crank to disengage the clutch elements, thereby causing thespool 67 to he loose and olier no resistance to the unwinding of theline 7 3 as the roproducer is progressively moved by the phonograph metor in the direction indicated by arrow in Fig. 1.

When the reproducer has reached the end of its travel, as controlled bythe adjustment of the attachment 35, the finger 24 will strike theportion 35 of the latter to cause the movement 01' the rod 32 andtripping of the plate 60 to move the nut 62 in position opposite thepaths of the arms 58 of the cscapenlont and thus release the latter andthe cam 59 and permit the clutch to be coupled and cause the line 73 tobe wound about the spool, which raises the reproducer and drags it intocontact with the attachment 33, thus effecting the purpose of theinvention by repeating the music. More specifically, when the drag-baris movedtoward the right by the interference of the attachment 35, asabove explained, the plate 60 is shifted to permit the escapement wheel58 tomake a quarter turn, and the cam being correspondingly'movcd bringsan end of its minor diameter to oppose the crank 70, and allows thespring 72 to as sert itself to couple the clutch elements and fix thespool to its arbor, which being new active winds in the line toaccomplish the reverse movement of the reproducer. During this step inthe operation, one of the escapement wheel arms 58 is directed towardthe fan and, being shorter than either of the others does not protrudewithin the path of travel of the fan-wings, so that the latter beingunrestrained allows th clock-work to operate and coincidentally regulatethe speed thereof. The clock-work continues to operate until the platehas again been shifted to afford a quarter turn to the wheel 58 andbring one of the longer arms thereof into the pathoi' the i'an, thusstopping the action of the clock-work and at the same time disengagingthe clutch, which occurs as the reproducer is lowered.

With the present invention, the operation of the return of thereproducer to make repetition of the music is accomplished by anindependent motor, is rapid in action, and works in an efficient mannerand without any apparent jar or shock.
